Re: [beagleboard] Re: BeagleBone Black - No HDMI Output

[achu4798]

Hello,

I am using Beagle bone Black Rev C with 7.11 image and I have connected the 
device to LCD monitor using micro HDMI to HDMI cable. Before it was working 
fine but suddenly it started showing blank screen.
I tried various steps:

1) reflashed the device 
2) parse-edid edid to check about monitor 
3) did xrandr --verbose with 1024x720@60 as well as 50 rate and changed the 
same in /boot/uEnv.txt
4) saw about the device connection also in /proc/cmdline also.
Everything was normal as before but it did is showing blank screen.

Please someone help me with this one.

By the way I am using sony Ericson HDMI cable. So, the use of low quality 
is outdated.


Gerald and Robert I am following this thread for past 2-3 days continously 
and tried almost all the steps in the comments but no use. Someone help me 
with this.



Thanks in advance

Regards,
Ashwin

> Hello Gerald,

I am Ashwin. I am using Beaglebone Black with 7.11 wheezy image with LCD 
monitor. Previously it was working fine.but suddenly it started to show 
blank screen. I have been following the thread about the HDMI issue in BBB 
closely and followed almost all the steps suggested by everyone but no use. 
I am still having the issue. 

I have done checking about the 
1) status of the device connected to hdmi port
2) parse-edid edid
3) changed the screen resolution and frame rate using xrandr as well as in 
/boot/uEnv,txt 
4) Even reflashed 2 times but no use.

I require your help with this one. Can you suggest me any other solution?


Thanks in Advance,
Regards,
Ashwin

Actually I am working on three BBB boards, and they have preinstalled linux 
3.8.13-bone70. Two of them are happy with our LCD screen(I do not why 
though, yes I had checked the link you send me Robert. I guess really it is 
exceptional case displaying on 1080@60 [smile] ). On one board I am having 
problem with LCD display I reinstalled linux3.8.13-bone41 accidentally, and 
upgraded to 3.8.13-bone70. After upgrade at least displaying for 2-3 
minutes, before installing bone41 It did not display anything. I am not 
sure whether they have exactly same u-boot version. Is it ok if I update 
you tommorow?

Actually we have three BBB boards, and two of them are perfectly displaying 
on our LCD screen with 1080@60 (I do not know why though, I have looked the 
lin k that you send me 
Robert). All BBBs came with preinstalled linux 3.8.13-bone-70. On one that 
has display problem I reinstalled linux 3.8.13-bone41 accidentally and 
after than I upgraded to bone70. I am not sure If they have exactly same 
u-boot version. Is it ok, If I update you tomorrow?

Hello Robert,
I have checked my u-boot version. On working two BBB boards u-boot version 
is U-Boot 2014.04-00015-gb4422bd. On problematic BBB board it is U-Boot 
2013.10-00016-ga0e6bc6. 
Do I need to upgrade my u-boot to the 2014.04-00015 version?
Thank you in advance.

Hello Gerald & Robert,
Actually I am working with three BBB boards, two of them are ok with LCD 
display I am using. They all have preinstalled linux 3.8.13-bone70. I had 
checked the link you send me Robert. (I guess it is really exceptional case 
that BBBs displaying on 1080@60 lcd screen). On one BBB that I had a 
problem I reinstalled linux 3.8.13-bone41 accidentally, and after upgraded 
to bone70. Before intallation bone41 it did not even display anything on 
LCD, but after upgrade to bone70 at least it is displayin debian logo for 
2-3 seconds. I am not sure whether they have same u-boot version. Is it ok 
if I update you tommorow?

Are they 'exactly' the same versions? Including the u-boot version?

I still think it's lucky one even works at full 1080p...

Yes one if those older kernels sorta worked, but HDMI audio was toast.  The
source for bone41/70 is available.. As you have the hardware, only you can
test the changes.

So you have one board that works and another that does not work with the
same exact software?

I did try to give defaul screen resolution in uEnv.txt as Glenn said. But 
it is just changing the size of the debian logo for 2-3 seconds and then 
screen turning to black again. I upgraded to linux 3.8.13-bone70 today from 
linux 3.8.13-bone41 just downloaded it ran ./install-me.sh then rebooted. I 
am working with two beaglebone black boards right now. One is perfectly 
running with lcd screen and hdmi cable without any modification to uEnv.xt

appreciate all your advice and help.

I assume you followed all the instructions on the Wiki, so I guess the

Then your cable and board is fine. Make sure you have the latest SW.

Re: [beagleboard] Re: BeagleBone Black - No HDMI Output

[glennbenson]

Gerald,

I am having the same problems as described above.

The one difference I appear to be getting is that during the initial boot, 
I get the BeagleBone logo appear in the top left of the screen. This also 
changes size depending on what resolution I set in uEnv.txt

After this image disappears and a little more time has passed, I get "No 
Signal" on my 32" TV or "Power Saving Mode HDMI" on my LG Flatron L246WH 
24" Monitor.

This suggests to me that the HDMI setup is working but something breaks it 
during the boot process.

Re: [beagleboard] Re: BeagleBone Black - No HDMI Output

[Chien-Yu Chen]

I've confirmed the cable isn't good. I plugged the cable into my Sony 
Ericsson Xperia Neo, there is output on my HDMI monitor. But nothing 
happens when connected to BBB.
I know there are different versions for the HDMI spec. Do you mean I have 
to use the cable that supports newer version?

It does not. It was too complicated for them to do as I understand it. I

[Tomas Espeleta]

Yeah.. it's a bit confusing: their page actually makes you think they do

Thank you very much Gerald!

As I understand it, the SDK from TI has no support for the HDMI display.
But, I would ask them and see what they say.

Re: [beagleboard] Re: BeagleBone Black - No HDMI Output

Could be this the reason why I can have a perfectly working 
non-accelerated-android working on my BBB (followed 
http://icculus.org/~hendersa/android/, with Robert Nelson's 3.8 kernel), 
while follwing these instructions 
http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide
 I 
get a "Video format not supported" on my TV?

I've tried changing uEnv.txt, changing the resolution to a very standard 
one, and it looked like it was ignored Is there any way to workaround 
this?


optargs=video=HDMI-A-1:640x480@60


I'd like to see TI's demo on my tv... even if it's with the old kernel   :)

The display driver takes over once it is launched. It does not use the
uENV.txt parameters. It uses the EDID.
